Title: Analysis of cardiac data
Inventor: MAREK SIRENDI
IPC: A61B5/352
Filed: 2018-09-07
Abstract: A method of analysing cardiac data provided for example by an electrocardiogram (ECG), cardioverter defibrillator or capnography, comprises determining a property of the data e.g. a mean RR interval, determined over a particular context length selected based on the property, for instance around 230 beats. This is compared with a threshold to indicate a probability of the patient experiencing a cardiac event within a risk window, which may be a probability density distribution. The threshold may be determined by training classifiers to classify properties of multiple heartbeats using a machine learning algorithm. The method may enable preventative action to be taken, or may enable determination of periods during which increased patient monitoring would be beneficial. Also disclosed is a method of training a hybrid classifier by combining classifiers based upon a performance metric, such as accuracy, sensitivity, specificity or precision.

Title: Boundary-aware object removal and content fill
Inventor: Sanjeev Tagra
IPC: H04N5/232
Filed: 2019-09-16
Abstract: An image processing application 200 for object removal and content fill comprises an object boundary module 252, an object intersection module 253, and a content filling module 254. The boundary module identifies a completed boundary for each object 212, 213, 214 of a set of objects in an image 211 by providing the object to a trained model. The intersection module determines a set of masks 260, 261. Each mask corresponds to an object of the set of objects and represents a region of the image defined by an intersection of the boundary of the object and the boundary of a target object to be removed from the image. The content filling module updates each mask by separately performing content filling on the corresponding region. The image processing application creates an output image 240 by merging each of the updated masks with portions of the image such that the removed object is no longer present in the user and the remaining objects 242, 243 are visible including the portions originally occluded by the deleted object. The application may include an object detection module 250 which detects the objects in the image and sends the objects to the boundary identification module.

Title: Real-time computer vision-based track monitoring
Inventor: Archie Marshall
IPC: B61L25/06
Filed: 2021-03-17
Abstract: A rail-vehicle mounted system (10, Fig.1) comprises a sensor unit 20 directed at a track 32 ahead of the vehicle 30 in the direction of motion. The sensor data may be LIDAR, SONAR or video data, and is analysed in real time to indicate track conditions. E.g. image analysis may detect objects on the track, a direction in which the track is proceeding, a status of railway points 34 or a track defect. If an object is detected, an emergency system may sound an alarm or apply brakes. The detected track direction may be used to anticipate track layout, e.g. speed modulation. Once the train’s future path is determined (e.g. using the points setting indicated by point tips (switch plates) 38, Fig.2C) a directional alarm can protect a region in the direction it will travel while ignoring other directions. The information may be communicated to other nearby systems or a central information store. Information received from them may be confirmed or updated.
